Abstract (en)
[origin: EP0803266A2] The present invention is for a guide wire with an improved flexible distal section with both a radiolucent coil 20 and radiopaque coil 15. The guide wire comprising a core wire 25 having a proximal end and a distal end, the proximal end of the core wire having a first diameter and the distal end having one or more reduced diameters, a radiolucent coil 20 surrounding the reduced diameter of the core wire, the radiolucent coil having a proximal end and a distal end, the radiolucent coil having a length that is shorter than the length of reduced diameter of the core wire, the proximal end of the radiolucent coil being fixedly mounted to the proximal end of the reduced diameter of the core wire, a radiopaque coil 15 surrounding the reduced diameter of the core wire, the radiopaque coil having a proximal end and a distal end, the radiopaque coil having a length that is shorter than the length of reduced diameter of the core wire such that the total length of the radiolucent coil and the radiopaque coil added together are approximately the same length as the reduced diameter of the core wire, the proximal end of the radiopaque coil being concentrically welded to the distal end of the radiolucent coil, the distal end of the radiopaque coil being welded to the distal end of the reduced diameter of the core wire forming a tip ball 30 and a welded spring brace 50 located distal of the welded connection between the radiolucent coil and the radiopaque coil, the welded spring brace attaching the radiopaque coil to the reduced diameter of the core wire. <IMAGE>
